FR Series elements are designed
for applications where high
vibration resistance as well as
high temperature stability are vital.
Typical industrial applications
include analytical equipment,
chemical plants, and mechanical
equipment. Small tolerances on
diameters allow problem-free
installation in protective tubes.
